Claude Is Down for Many, Anthropic Says It's Investigating the Outage

My take: I'll be honest even though Claude is my daily tool: this morning it went down for tens of thousands of people at once, with over 8,000 reports on Downdetector in the US alone. Anthropic confirmed an elevated error rate and said a fix was already on the way. What I find fascinating (and a little ironic) is the root cause: a bug in Claude Code's sub-agent architecture that made them multiply instead of finishing the task, an infinite loop that ate up the platform's resources. Agents making more agents until the house comes down, like the sorcerer's apprentice conjuring brooms with no way to stop them. This isn't a dumb server glitch: it reminds us that multi-agent systems still have serious blind spots in production, and I say that as someone who builds with them. They fixed it within hours, but the fact that it happened right before Anthropic's IPO doesn't slip past anyone. Of course, that's just my opinion.
